In-memory Backend In-memory blockchain backend.

Modules§

cache
fork_db
in_memory_db: The in memory DB
inspector: Anvil specific [revm::Inspector] implementation
monad 🔒 monad: Monad-specific execution and context helpers for the in-memory backend.
optimismoptimism: Optimism-specific transact helpers for the in-memory backend.
state: Support for generating the state root for memdb storage
storage: In-memory blockchain storage

Backend: Gives access to the [revm::Database]
EnvelopeExecution 🔒
ForkCacheNamespace 🔒: Identifies one endpoint’s persisted cache files across all blocks of a source chain.
ForkCacheSource 🔒: Identifies the endpoint that supplied the most recently committed fork.
GasEstimateCallOptions 🔒
PreparedCall 🔒
SimulationHandler 🔒: Ethereum handler that skips blob fee cap validation for non-validating calls with a zero cap.
SimulationPrecompileOverrides 🔒
StagedForkCacheLease 🔒: Keeps a staged fork from persisting remote state unless it is committed.
StagedForkCacheLeaseInner 🔒
StagedForkDbUser 🔒: Couples an asynchronous staged-database user to its rollback lease.
StagedForkReset 🔒: Fully prepared fork replacement awaiting an atomic backend commit.
StagedMemoryReset 🔒: Fully prepared in-memory replacement awaiting an atomic backend commit.
StateSnapshot 🔒
TypedCallOverrides 🔒

BlockRequest: A block request, which includes the Pool Transactions if it’s Pending
CallTxEnv 🔒
EnvelopeExecutionKind 🔒
MonadExecutionContext 🔒 monad

HOLESKY_DEPOSIT_CONTRACT_ADDRESS 🔒
MIN_CREATE_GAS
MIN_TRANSACTION_GAS
SEPOLIA_DEPOSIT_CONTRACT_ADDRESS 🔒
SIMULATE_GAS_CAP 🔒: Maximum cumulative gas available to one eth_simulateV1 request.
TEMPO_RPC_SIMULATION_CONTEXT 🔒: Fixed transaction context for direct Tempo RPC simulations.

BackendInspectormonad and optimism: Marker trait that abstracts over the per-network inspector trait bounds required by the in-memory backend. The OP bound is only included when the optimism feature is enabled.
DatabaseRef: Helper trait that combines revm::DatabaseRef with Debug. This is needed because alloy-evm requires Debug on Database implementations. With trait upcasting now stable, we can now upcast from this trait to revm::DatabaseRef.
IntoInstructionResult: Converts a halt reason into an [InstructionResult].

apply_tempo_envelope_identity 🔒
arbitrum_replay_block_number 🔒
build_rpc_transaction 🔒
call_config_from_tracer_config 🔒
commit_cache 🔒: Commits a fully executed candidate cache to the live database.
foundry_header 🔒: Wraps an Ethereum-shaped header in the selected network’s consensus header.
genesis_header 🔒: Creates an Ethereum-shaped genesis header from the EVM environment.
get_pool_transactions_nonce 🔒: Get max nonce from transaction pool by address.
is_arbitrum
mock_tempo_signature 🔒
monad_execution_context_at 🔒 monad
next_monad_context 🔒 monad
noop_before_transaction 🔒
noop_on_execution_error 🔒
preserve_deleted_storage 🔒
previously_deleted_accounts 🔒
prove_storage: Prove a storage key’s existence or nonexistence in the account’s storage trie.
rehash 🔒: Replaces the cached hash of a [Signed] transaction, preserving the inner tx and signature.
sanitize_simulation_blocks 🔒
simulate_rpc_error 🔒
simulate_transaction_error 🔒
tempo_db_err 🔒: Converts a Tempo error into an anvil [DatabaseError].
tempo_nonce 🔒
transaction_build: Creates a AnyRpcTransaction as it’s expected for the eth RPC api from storage data
unpack_execution_result 🔒: Unpacks an [ExecutionResult] into its exit reason, gas used, output, and logs.

MonadReplayContext 🔒 monad
OpCallDepositInfo 🔒 optimism: Side-channel container for OP-specific deposit info produced by Backend::build_call_env_with_base and consumed by the OP transact path.
